Product Description

AEM’s 4-Channel Wideband Air/Fuel UEGO Controller allows users to simultaneously monitor individual cylinder Air/Fuel Ratios (AFR) on up to four cylinders, and can monitor up to 8 individual cylinders with the addition of a second unit (up to 16 cylinders with four controllers). The AEM 4-Channel Wideband Air/Fuel UEGO Controller can increase both engine performance and reliability. It is the most affordable multi-channel air/fuel controller available, and is a must for anyone using an engine management system or data logger to monitor and/or tune individual cylinder AFR.

UNMATCHED CONTENT AND ACCURACY
AEM has engineered several features into the 4-Channel Wideband UEGO Controller that provide unmatched accuracy and feature content:

Designed to Withstand Extreme Temperatures
AEM’s 4-Channel Wideband Air/Fuel UEGO Controller uses specially-designed, stainless-steel sensor mounting bungs that help the sensors withstand the extreme temperatures of pre-turbo exhaust ports. The fins of the bung reduce the temperature of the sensor body to extend its life, and the extended bung length allows only the sensor tip to protrude into the exhaust flow to minimize flow restriction.

CAN bus or Analog Outputs for Data Logging
AEM’s 4-Channel Wideband Air/Fuel UEGO
Controller can be integrated with almost any data logger or engine management system through 4 unique differential analog outputs or the AEMnet CAN bus datastream output. The CAN bus datastream output is compatible with most programmable ECUs, data loggers, dashes and dyno systems, and provides users with the ability to data log for each individual cylinder without tying up all of the ECU’s channels.

Laboratory-Calibrated Sensors
Bosch 4.2LSU sensors are laboratory calibrated at the factory. They deliver unsurpassed accuracy and NEVER require free-air calibration when used with an AEM air/fuel ratio controller.

Channel Status and Error Lights AEM’s 4-Channel Wideband Air/Fuel UEGO
Controller includes green and red LED lights for each channel that provide immediate reference to system status or to indicate an error. The LEDs provide confidence that the system is operational and assist in troubleshooting if an error occurs.

Weather-Resistant/Shock-Resistant Housing, Harness, and Communication Connections
The 4-Channel Wideband Air/Fuel UEGO Controller is housed in a weather- and shock-resistant housing that repels dirt, dust and debris and is vibration resistant. Mount it virtually anywhere!
